Question for others that have a 2013 6.7 cummins.
Don't know if its a programing issue for smog related issues or or something else
. When coasting down as like coming to a stoplight then it turns green before you stop, so you step on the throttle to go and.....the engine doesn't immediately power up. Its like there is almost a second that the engine doesn't want to pickup up rpm's then suddenly it does. Even does this with a partial coast down then a sudden/quick jump on the throttle. Kind of like back in the days of carburetors and the acelerator pump wasn't pumping fuel when you opened up the throttle and the engine bogged down momentarily then took off.
Its almost like the ecm is waiting for the turbo vanes to close down so the turbo can spool up before fuel is added to powerup? I would guess this would reduce black smoke ( coal) and loading up the dpf....just a wild guess/assumption
on my part. No codes are being thrown, 5000 miles on the clock in 2 months of ownership. Haven't even called the dealer yet to ask about it as its very minor but still noticeable.
Other then this oddball quirk I have extremely happy with this truck. Getting about 2 mpg better then my 07.5 did, smoother riding, quieter cab and of course all the extra comfort features over the 07.5. Still have just short of a 1/4 tank of def fluid.
Remember not to talk bad about farmers with your mouth full!
